The Dave Lennox Signature Collection price varies by model, capacity, installation complexity and region; buyers typically pay between $4,000 and $12,000 for a complete furnace or air conditioner install. This article lists common price ranges, per-ton and per-unit estimates, and the main factors that drive the final price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Gas Furnace (Signature) | $2,500 | $4,500 | $7,500 | Includes moderate installation; 80%-98% AFUE options |
| AC/Heat Pump (Signature) | $2,000 | $4,000 | $8,000 | $1,200-$3,500 per ton depending on SEER/efficiency |
| Complete Split System | $4,000 | $8,000 | $12,000 | Furnace + outdoor unit + basic ductwork |
| High-End Installation | $7,000 | $11,000 | $18,000 | Includes zoning, new ducts, premium controls |
Typical Total Price For A Lennox Signature Furnace Or AC
Most homeowners buying a Dave Lennox Signature Collection system pay $4,000-$12,000 total for equipment plus standard installation. A typical split-system with a mid-efficiency Signature furnace and 3-ton AC averages about $8,000 delivered and installed.
Assumptions: Single-family home, 1.5-2.5 HVAC tons, suburban labor rates, standard single-story duct layout.
Materials, Labor, Equipment, and Permits In A Quote
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $1,500-$6,500 | $750-$2,500 | $2,000-$8,000 | $50-$400 | $75-$400 |
| Includes furnace/coil/pan/filters | ~6-20 hours | Outdoor condensing unit per ton: $1,200-$3,500 | Local mechanical permit fees | Old unit removal and disposal |
Equipment is often the largest single line item, typically 40%-70% of the total quote for Signature models.
How Capacity, Efficiency, And SEER/AFUE Change Price
Unit capacity and efficiency are primary price levers: 2-3 ton systems cost less than 3.5-5 ton systems, and higher SEER or AFUE raises equipment price. Expect a $800-$2,500 premium when moving from standard to high-efficiency Signature models (e.g., 16 SEER to 20+ SEER or 80% AFUE to 95%+ AFUE).
Numeric thresholds: 2.5 tons vs 3.5 tons, 14-16 SEER vs 18-21 SEER, 80% AFUE vs 95%+ AFUE.
Site Conditions And Installation Complexity That Affect The Quote
Hard-to-reach equipment, extensive ductwork replacement, crawlspace access, multi-story runs, and adding zoning raise labor and material costs. Replacing ductwork can add $2,000-$8,000 depending on square footage and whether it’s partial or full replacement.
Examples: 500-1,000 sq ft partial duct repair = $1,000-$3,000; whole-house duct replacement (2,000 sq ft) = $4,000-$8,000.
Ways To Reduce Dave Lennox Signature Collection Price Without Sacrificing Function
Buyers can reduce cost by selecting a slightly lower SEER/AFUE model, keeping existing ducts, scheduling off-season installs, or getting multiple detailed quotes. Choosing a 16-18 SEER Signature unit instead of top-tier 20+ SEER often saves $1,000-$2,500 with only modest efficiency loss.
Practical tips: bundle furnace and AC purchase, complete minor prep work before install, request itemized quotes to compare line items.
Real-World Quote Examples With Specs And Labor Hours
| Example | Specs | Labor Hours | Per-Unit Rates | Total |
|---|---|---|---|---|
| Basic Replace | 2.5-ton AC + 80% AFUE furnace | 8-12 hours | AC $1,400/ton; furnace $2,200 | $4,000-$5,500 |
| Mid Upgrade | 3-ton AC 18 SEER + 95% AFUE Signature furnace | 12-16 hours | AC $2,000/ton; furnace $3,500 | $7,000-$9,000 |
| Premium Install | 4-ton 20+ SEER + 98% AFUE + zoning | 18-30 hours | AC $2,500-$3,200/ton; zoning $1,200-$2,500 | $11,000-$18,000 |
These examples show how capacity, efficiency, and added features like zoning multiply both equipment and labor costs.
Seasonal Timing, Regional Price Differences, And Contractor Rates
Prices are 5%-20% higher in peak summer/winter demand months and typically 10%-30% higher in high-cost urban markets. Expect labor rates around $75-$125 per hour in many U.S. areas; higher rates in metro coastal markets can push quotes up accordingly.
Regional delta: rural/suburban baseline; +10%-20% urban; +5%-15% Northeast/West Coast compared to Midwest.
